Strength in Numbers: November’s Best Environmental Books
An important theme runs through November's new environmental books: We're stronger together than apart.
For one author that means fostering the ability of people and wildlife to coexist. For a group of experts, it involves working hard to adapt to the threats of climate change. And two new books make the case for diversifying the environmental movement — because we all need each other.
You'll find our selections for November's 12 most noteworthy eco-books below. Check them out, pick the ones (or pairs) that are best for you, and then prepare to do some illuminating and world-changing reading — and maybe pull a few friends along while you're at it.
Our Wild Calling: How Connecting With Animals Can Transform Our Lives — and Save Theirs by Richard Louv
The author of the classic Last Child in the Woods returns with a howling-good new book about the scientific, moral, ethical and spiritual need for human-animal coexistence. (Hint: It will help the animals, too.)
Building a Resilient Tomorrow: How to Prepare for the Coming Climate Disruption by Alice C. Hill and Leonardo Martinez-Diaz
A New Coast: Strategies for Responding to Devastating Storms and Rising Seas by Jeffrey Peterson
With climate change already causing problems for coasts and other communities and habitats around the world, we'd better start planning how to adapt for a risky and uncertain future. These two new books by former officials in the Obama administration concentrate on developing actionable successes to minimize the damage and ensure that the systems we depend upon can persist.
Engage, Connect, Protect: Empowering Diverse Youth as Environmental Leaders by Angelou Ezeilo
The founder of the Greening Youth Foundation provides a critique of the too-white environmental movement and a toolkit for engaging younger participants from African-American, Latino and Native American communities.
Latinx Environmentalisms: Place, Justice, and the Decolonial edited by Sarah D. Wald, David J. Vázquez, Priscilla Solis Ybarra and Sarah Jaquette Ray
More than a dozen top minds come together to examine thoughts and cultural processes otherwise ignored by the environmental movement.
The Case for the Green New Deal by Ann Pettifor
A Planet to Win: Why We Need a Green New Deal by Kate Aronoff, Alyssa Battistoni, Daniel Aldana Cohen and Thea Riofrancos
Radical publisher Verso Books brings us two new volumes about the Green New Deal this month. Each tackles the topic from a different perspective (the first covers economics, while the second focuses on politics), but both see it as a critical way to address the inequality that causes so many of the world's problems.
American Resistance: From the Women’s March to the Blue Wave by Dana R. Fisher
What can we learn from the wave of resistance that blossomed after the election of President Donald Trump? And can efforts like the Climate Strike make a difference in 2020 and beyond? Fisher looks deep into the data to reveal how this movement can keep making progress.
Common Sense for the 21st Century: Only Nonviolent Rebellion Can Now Stop Climate Breakdown and Social Collapse by Roger Hallam
One of the cofounders of Extinction Rebellion provides a call to action inspired by Thomas Paine's original Revolutionary War-era Common Sense but updated for a modern, warmer world and the need for civil disobedience.
All Hell Breaking Loose: The Pentagon’s Perspective on Climate Change by Michael T. Klare
If the Pentagon worries about floods, disease, drought, climate refugees and so many other threats, then the rest of us should, too.
Recycling by Finn Arne Jørgensen
A fascinating examination of how we transform some things into other things — physically and culturally. This book follows a selection of products through the supply chain, from creation to disposal to re-creation. Along the way it aims to prove that recycling isn't just important for the planet; it also plays a vital psychological role for those of us participating in the process.
Science Be Dammed: How Ignoring Inconvenient Science Drained the Colorado River by Eric Kuhn and John Fleck
The authors examine the Colorado River's history of mismanagement, providing both a cautionary tale and a look ahead at how we can (hopefully) resolve the mistakes of the past — and maybe avoid similar problems on other rivers.
That's our list for this month, but you'll find dozens of other recent eco-books in the "Revelator Reads" archive.

By Jacob L. Steenwyk and Antonis Rokas
From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
When Looking Through a Microscope Isn’t Close Enough.<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>
Several Different Fungal Hybrids Cause Human Disease.<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p>
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection. (Right) Cryptococcus yeasts, including ones that are hybrids, can cause life-threatening infections in primarily immunocompromised people. Centers for Disease Control and Prevention<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>
The Evolutionary Origin of an Aspergillus Hybrid.<p>Multiple evolutionary paths can lead to the emergence of hybrids. One path is through mating, just as the horse and donkey mate to create a mule. Another path is through the merging or fusion of genetic material from cells of different species.</p><p>It is this second path that appears to have been taken by our fungus. <em>A. latus</em> appears to have two of almost everything compared to its parental species: twice the genome size, twice the total number of genes and so on. But unlike other hybrids, which are often sterile like the mule, we found that <em>A. latus</em> is capable of reproducing both asexually and sexually.</p><p>But how distinct were the parents of <em>A. latus</em>? By comparing the parts contributed by each parent in the <em>A. latus</em> genome, we estimate that its parents are approximately 93% genetically similar, which is about as related as we humans are with lemurs. In other words, <em>A. latus</em>, an agent of infectious disease, is the fungal equivalent of a human-lemur hybrid.</p>
How A. Latus Differs From its Parents.<p>Elucidating the identity of closely related fungal pathogens and how they differ from each other in infection-relevant characteristics is a key step toward reducing the burden of fungal disease. For example, we found that <em>A. latus</em> was three times more resistant than <em>A. nidulans</em>, the species it was originally identified as using microscopy-based methods, to one of the most common antifungal drugs, <a href="https://www.drugbank.ca/drugs/DB00520" target="_blank">caspofungin</a>. This result provides a clear example of the potential importance of accurate identification of the <em>Aspergillus</em> pathogen causing an infection.</p><p>We also examined how <em>A. latus</em> and <em>A. nidulans</em> interact with cells from our immune system. We found that immune cells were less efficient at combating <em>A. latus</em> compared to <em>A. nidulans</em>, suggesting the hybrid fungus may be trickier for our immune systems to identify and destroy.</p><p>In the midst of the COVID-19 pandemic, our quest to understand <em>Aspergillus</em> pathogens is becoming more urgent. Growing evidence suggests that <a href="https://doi.org/10.1111/myc.13096" target="_blank">a fraction of COVID-19 patients are also infected with <em>Aspergillus</em>.</a> More worrying is that these <a href="https://doi.org/10.3201/eid2607.201603" target="_blank">secondary <em>Aspergillus</em> infections</a> can worsen the clinical outcomes for those infected with the novel coronavirus. That being said, we stress that little is known about <em>Aspergillus</em> infections in COVID-19 patients due to a lack of systematic testing, and none of the infections identified so far appear to have been caused by hybrids.</p><p>So, when it comes to hybrids, some are fantastic (the minotaur), some are helpful (the mule) and some are dangerous (<em>Aspergillus latus</em>). Understanding more about the biology of <em>Aspergillus latus</em> may help in our understanding of how microbial pathogens arise and how to best prevent and combat their infections.</p>

This past Wednesday, when some previously hard-hit countries were able to register daily COVID-19 infections in the single digits, the Navajo Nation – a 71,000 square-kilometer (27,000-square-mile) expanse of the western US – reported 54 new cases of what's referred to locally as "Dikos Ntsaaígíí-19."
The Navajo Nation covers the corners of three different states. Google Maps

World Environment Day: A Time to Consider the Planet We’ll Return To, and Decide How to Care for It Going Forward
It's a different kind of World Environment Day this year. In prior years, it might have been enough to plant a tree, spend some extra time in the garden, or teach kids the importance of recycling. This year we have heavier tasks at hand. It's been months since we've been able to spend sufficient time outside, and as we lustfully watch the beauty of a new spring through our kitchen's glass windows, we have to decide how we'll interact with the natural world on our release, and how we can prevent, or be equipped to handle, future threats against our wellbeing.
